The upper member 17., provided with contact tips 191 2G, is adz'ipted for engagement with the socket M1, and the lower memher 18, provided with contact tips 19, 20, is adapted for engagement with the socket 22. Extending formirdly from the body 1 1 between the members 17, 18 is a guide rod 23 raving the free end thereof mounted to slide in an apertured hearing block 24 mounted on one of the supports 2, the said guide rod being encircled by an expansible spring 25, having one end thereof abutting against the body 14 and the other end thereof abutting against the bearing block 2stto normally rcso that when it is desired to move the plug into closed position, to engage the sockets 21, 22, the mentioned plug must be operated against the action of ti pring by exert in a pressure on the knob 16 li/lounted Within the member 17 and extending longitudinally thereto are spaced wires 26, 2?, the WllO 26 having the tori ard end thereof connected to the upper contact tip 19 of the member 17 and the ire 27 having the forward end thereof connected to the lower contact tip 20 of the member 1 the mentioned Wires 26 and 2? being spaced apart and properly insulated from one an oth'en The other end of the Wire 26 tern1i mates in springcoil made of {L conduct ing material such as copper and connected to Wire 2 secured to the inner side of the box 16'. In a siiiiilar n'ianner the other end. the wire 27 is connected to a spring coil 30 similar to the spring coil 28, the iuentioned coil being connected to a Wire 31, similar to the "Wil'Q- 29, but spaced insulated therefrom and secured to the inner side of the box The Wire 29, extending around the inner side of the box is connected to a binding post secured to one of the sides oi. the box and extending exteriorly the cot and the Wire 81 is connected toa binding posl; 33' secured to the same side of the box and adjacent the binding; post 32. in a similar manner wires 3%, 35 are mounted within the lower member 18, 5 the said wires being spaced apart and relalively insulated with an end of the wire 34 connected to the upper contact tip 19 of the member l8 and an end of the wire 35 connected to the lower contact tip 20 of the 10 member in, the other end of the wire be ing COlllltiQllQtl to a coil spring 36, connected to awiri 37, secured to the inner side of the be); 10, the other end of the wire being connected to a similar coil spring connectcd to a wire 39 secured to the inner side of the box 10, the wires 37, 39 being spaced apart and insulated similarly to the wires 29, 31. The wires 37, 39 extend around the inner side of the box 10 and have their ends connected to spaced relatively insulated binding posts &0, 41, arranged oppositely to the binding posts 32, 355, the wire 37 being connected to the binding post il and the wire 39 being connected to the binding 95 post l0.

The socket 21 is rigidly mounted upon a. cross piece 42 extending; horizontally within the box 10 and the mentioned socket consists of spring-like members l3, l4, relatively soispaced apart and insulated at their inner ends and having their outer or free ends flared, the mentioned members ltl, ll being held in spaced relation by z. rcn'iovable insulated bar do, it being understood that one of the sockets 21 is arranged oppositely to each oi. the members 17 so that. when the plugs 13 are moved to closed position, the contact tips 19, 20 of each ot the members 17 will engage the members 43, all. respectively of the sockets 2i. 'lhe socket .22 is similar to'the socket 521 and is arranged beneath the socket 21, the nieintioneiil socket being: spaced from the socket 2i and insulated therefrom by a suitable insulation to. The socket 522 embodies more particularly spaced relatively insulated spring-like members 47, d8 having their outer or free ends flared, the mentioned free ends of the members -17, 4-8 being normally held apart by an insulated bar 49. Now when one of the plugs 13 is moved into closed position, the contact tips 1.9, 20 of the member 17 will not only enga the members 43, 44 respectively, but the contact tips 19, 20 of the member 18, operable with the member 17, will engage the members 47, 48 respectively. The inner end of the member 43 is connected to a binding post 50 and the inner end of the member =l-l is connected to an adjacent binding post 531 solo a similar manner the inner end of the member t? is connected to a binding post 52 and the inner end of the member 48 is con necled to an adjacent binding post 52-), the binding posts ot' the upper sockets being: arranged in a horizontal row and the binding an 1,105, l85

will. understood that my device can be used in connection With-other telegraph and telephone circuits than are shown in 6 i and the device can also be used in combination with a telegraph and. local telephone system, particularly railroad telegraph and telephone systems, in which it is desired at all times to have, ready access to 1 0 local telephone With a device of the class described, the operation of one of the plugs secures the automatic release of other circuits and when device is used in connection with telegraph systems, batteries for the resonators need noo c provided and an in-zil pendent relay is dispensed with, the circuit being; accomplished by cutting directly into the main line relay.

It will therefore be apparent from the foregoing description that the plugs 13, arranger mentioned with respect to the sockets 21 consiss primarily of a combinaof two members, namely, the members.

1? and 18, for engagement with the respective sockets 21, 22, and whereby, when the plugs are related to the sockets as disclosed hereiofore it will be possible to make direct connection besween main lines and local lines, when used either as a telephone or no telegraph exchange or both, and whereby, further, a number of plugs used in connection with the respective sockets therefor permit of cutting in several independent 'main, lines with independent local lines.

By arranging the plugs so that the throwing in of one plug will cut out any others previously thrown into contact with their respective sockets, a structure is provided which is automatic in operation as regards the making and breaking of circuits between main and local lines.
